108例鼻咽未分化癌的放化疗疗效分析

鼻咽未分化癌发病率较低，约占1％～10％，有关其放化疗的报道较少，本文对本院1983年至1996年收治的108例鼻咽未分化癌放化疗疗效进行回顾性分析，并就该病的诊治进行探讨。

宫颈鳞癌和食管鳞癌中Fas基因表达及其与放射敏感性的关系

用免疫组化法对 52例宫颈鳞癌和食管鳞癌标本中 Fas基因蛋白进行研究 ,并探讨其与近期放疗效果的关系。结果显示 ,Fas蛋白在宫颈鳞癌和食管鳞癌中表达分别为48.3 8%和 61 .90 % ,Fas蛋白在高分化癌中表达率高于低分化者 ( P<0 .0 5) ,与病期无关 ( P>0 .0 5)。在宫颈鳞癌中 ,Fas蛋白表达高者放疗效果较好 ( P<0 .0 5) ,食管鳞癌 Fas表达与放疗效果无明显相关 ,提示 Fas表达与放射敏感性有一定关系 ,对放疗预后判断有一定价值     

鼻咽癌颈部转移性淋巴结的超声造影特征及时间强度曲线分析

Objective To study the character of cervical lymph nodes metastasis in nasopharyngeal carcinoma(NPC) by contrast-enhanced uhrasonography(CEUS) and time-intensity curve. Methods Forty-one lymph nodes of metastasis from 32 patients were studied by CEUS. The enhancement of echogenicity was evaluated,and the time-intensity curve was analyzed. Results Of the 41 lymph nodes examined, 10 (24.4%) showed intense homogeneous enhancement by CEUS, 23 (56.1%) showed inhomogeneous enhancement and 8 (19.5 %) showed scarce intranodal enhancement. There were 20 (48.8%) lymph nodes showed necrosis. Most of the lymph nodes (92.7%) showed peripheral type blood flow, 3 (7.3) % showed mixed type blood flow. There were significant differences in them(P < 0.01). The time-intensity curve displayed steeply in upslope, and gently in decent. The arrival time(AT), time to peak(TTP), peak intensity (PI) ,area and gradient were (7.2±2.5)s,(7.6±2.3)s,(9.5±3.3)dB,(203.4±45.7)dB· s,1.2±0.5 respectively. Between the lymph nodes with envelope infringed and not, there were significant differences in PI and area, while there were not significant differences in AT, TTP and gradient. Conclusions The metastasis cervical lymph nodes of NPC had specific character by CEUS and time-intensity curve. In this way,it may help us to diagnosis cervical lymph nodes metastasis of NPC,and provide more information for the therapy and prognosis judgement.
